Ngati mukufuna zotumiza mitundu yonse 3, chabe kuwonjezera chikhalidwe zina mtundu wina wa fano.

Kukopera zichitike monga izi: buku (chithunzi 1, chifaniziro 2).

Ifeyo ntchitoyi kutsitsa kwa PC makina, mukhoza kutero

buku ($ _ owona [ 'file_upload'] [ "tmp_name"], "1.jpg")

Ndiko kuti, wapamwamba liti liwonerere ndi dzina 1.jpg. Izi si zolondola kwathunthu. Pankhaniyi, ndiye chitsanzo. Dzina file ndi zonse zofunika mwachindunji osiyana, ndipo mwachindunji kutambasuka malinga pa wapamwamba.

Kudziwa kutambasuka kungakhale njira zosiyanasiyana. Izi zidalira pa mapulogalamu a erudition. Njira imodzi yachangu kuti (a kusiyana kwa magawo a masekondi) kudziwa kutambasuka kwa - izi ndi malamulo lotsatira.
